CRMS.CRWMS bit shall be set to 1 on controllers compliant with versions
later than NVMe 1.4.

The first version later than NVMe 1.4 is NVMe 2.0

Let's claim compliance with NVMe 2.0 such that a follow up patch can
set the CRMS.CRWMS bit.

This is needed since CC.CRIME is only writable when both CRMS.CRIMS
and CRMS.CRWMS is set.
